Anthony Scaramucci has been removed as White House communications director at the request of White House Chief of Staff John F. Kelly, just 10 days after being named to the job, according to two people with knowledge of the decision.

Scaramucci’s brief tenure in the role had been marked by turmoil as he feuded publicly with former White House chief of staff Reince Priebus. Scaramucci’s arrival at the White House prompted press secretary Sean Spicer to resign in protest.

The abrupt decision signals that Kelly is moving quickly to assert control over the West Wing, which has been characterized by interpersonal disputes and power struggles during President Trump’s six months in office.

The retired Marine general, who was sworn in Monday morning, was brought into the White House in the hope that he will bring military-style discipline to Trump’s staff. He has been fully empowered by the president to make significant changes to the organization, White House officials and outside advisers said.

The White House confirmed Scaramucci’s departure in a statement on Monday afternoon.

“Anthony Scaramucci will be leaving his role as White House Communications Director,” said a statement attributed to the White House Press Secretary, though it was unclear whether it was from Spicer or the incoming press secretary, Sarah Huckabee Sanders. “Mr. Scaramucci felt it was best to give Chief of Staff John Kelly a clean slate and the ability to build his own team. We wish him all the best.”
